You Need This Absolutely TREMENDOUS add-on! I have wildly disorganized work habits, and I'm indecisive, too, so it's not uncommon for me to have 144 tabs open, as I do right now.

I use Tree Tabs (also fantastic) to group them, usually four or five groups per page. Up to now, the FireFox menu showed only the active tab name, which didn't always make it clear what window/group that was. Now it's easy to see which window is Personal stuff, and so on.

And wiith Winger I don't have to go to the appropriate page when a question pops into my head. Just open the URL, and send the tab to the page it belongs in. This is super helpful when you don't actually want to look at the page right away — kind of like a detour with no time penalty.

Winger works flawlessly with Tree Tabs, the documentation is clear and very detailed, and it's free! These add-ons together make FireFox so much handier than Chrome or Safari I could really live without them. Amazing Winger has only 28 users at this writing.
